• Lipoxygenases in mammals have been found in the lung, platelets, and white cells. They are enzymes capable of oxidizing arachiodonic acid into hydroperoxy- eicosatetraenoic acids (HPETE S ) and their stable products hydroxyeicosatetraenoic acids ((HETEs). Lipoxygenases are classified according to the position in the arachidonic acid which is oxygenated. Platelets metabolize arachidonic acid to 12-HETE, while polymorphonuclear leukocytes contain 5 and 15 lipoxygenases. It is known that 12-HET E and 5, 12-diHETE are chemotactic for human neutrophilis and eosinophils, and may augment the inflammation process.
• 5-HPETE is known to be a precursor of slow-reacting substance of anaphylaxis(SRS-A).

• the net pmoles of 5-HETE are obtained by substracting the pmoles of 5-HETE in the tubes containing buffer alone (blank) from the pmoles of 5-HETE in the tubes containing buffer and cells (control). The ability of the test compounds to modulate the activity of this enzyme is determined by a decrease or increase in the net amount of 5-HETE produced.
• the therapeutic compounds of this invention may be administered to a mammal alone or in combination with pharmaceutically acceptable carriers, the proportion of which is determined by the solubility and chemical nature of the compound, chosen route of administration and standard pharmaceutical practice.

He will generally wish to initiate treatment with small dosages substantially less than the optimum dose of the compound and increase the dosage by small increments until the optimum effect under the circumstances is reached.
